2 Introduction

The Hart Scientific Model 9105/9107 dry-well calibrator may be used as a por

-

table instrument for calibration of temperature probes. The 9105 operates over

the range of –25°C and 140°C. The 9107 operates over the range of –45°C to

140°C.

These dry-well calibrators feature an interchangeable aluminum probe sleeve

along with 4 fixed wells. The temperature is accurately controlled by Hart's

precision temperature controller.

The calibrator controller uses a precision platinum RTD as a sensor and con

-

trols the well temperature with thermoelectric modules. The LED front panel

display continuously shows the current well temperature. The temperature may

be easily set with the control buttons to any desired temperature within the

specified range.

The 9105/9107 dry-well calibrator was designed for portability, moderate cost,

and ease of operation. With proper use the instrument should provide continued

accurate calibration of temperature sensors and devices. The user should be fa-

miliar with the safety guidelines and operating procedures of the calibrator as

described in the User’s Guide.

3 Specifications and Environmental Conditions

4 Safety Guidelines

•

Operate the instrument in room temperatures between 5–50°C

(41–122°F). Allow sufficient air circulation by leaving at least 6 inches of

space between the instrument and nearby objects. DO NOT place under a

cabinet or other structure. Allow for overhead clearance.

•

The dry-well is a precision instrument. Although it has been designed for

optimum durability and trouble free operation, it must be handled with

care. Always carry the unit in an upright position to prevent the probe

sleeves from dropping out. The convenient fold-up handle allows one

hand carrying. The instrument should not be operated in excessively wet,

oily, dusty, or dirty environments. It is important to keep the well of the

instrument clean and clear of any foreign matter. DO NOT operate near

flammable materials.

•

DO NOT use fluids to clean out the well.

• The instrument can generate extreme temperatures. Precautions must be

taken to prevent personal injury or damage to objects. Probes may be ex-

tremely hot or cold when removed from the instrument. Cautiously handle

probes to prevent personal injury. Always use the special sleeve tongs that

are supplied with the calibrator to remove the sleeve. Carefully place

probes on a heat/cold resistant surface or rack until they are at room tem-

perature. Never place any objects other than the special probe sleeves sup-

plied with the calibrator into the well.

• Use only a grounded AC mains supply of the appropriate voltage to

power the instrument. The Model 9105 dry-well requires 3 amps SB at

115 VAC (±10%), 50/60 Hz, 1.6 amps T at 230 VAC (±10%). The Model

9107 dry-well requires 4 amps SB at 115 VAC (±10%), 50/60 Hz, 3.15

amps T at 230 VAC (±10%).

•

Before initial use, after transport, and anytime the dry-well has not been

energized for more than 10 days, the instrument needs to be energized for

a “dry-out” period of 1-2 hours before it can be assumed to meet all of the

safety requirements of the IEC 1010-1.

•

The instrument is equipped with operator accessible fuses. If a fuse

blows, it may be due to a power surge or failure of a component. Replace

the fuse once. If the fuse blows a second time, it is likely caused by fail

-

ure of a component part. If this occurs, contact Hart Scientific Customer

Service. Always replace the fuse with one of the same rating, voltage, and

type. Never replace the fuse with one of a higher current rating.

•

If a mains supply power fluctuation occurs, immediately turn off the in

-

strument. Power bumps from brown-outs and black-outs could damage

9105/9107 11

4 Safety Guidelines

the instrument. Wait until the power has stabilized before re-energizing

the instrument.

12 Hart Scientific

4 Safety Guidelines

5 Quick Start

5.1 Unpacking

Unpack the dry-well carefully and inspect it for any damage that may have oc

-

curred during shipment. If there is shipping damage, notify the carrier

immediately.

Verify that the following components are present:

•

9105 or 9107 Dry-well

•

2173 Insert, 1/4” Aluminum

•

Power Cord

•

Manual

•

Two Well Insulators (9107 only)

• Tongs (insert removal tool)

5.2 Set-up

Place the calibrator on a flat surface with at least 6 inches of free space around

the instrument. Overhead clearance is required. DO NOT place under a cabinet

or structure. Plug the power cord into a grounded mains outlet. Observe that the

nominal voltage corresponds to that indicated on the back of the calibrator.

Carefully insert the probe sleeve into the well. Probe sleeves should be of the

smallest hole diameter possible still allowing the probe to slide in and out eas

-

ily. Sleeves of various sizes are available for Hart Scientific. The well must be

clear of any foreign objects, dirt and grit before the sleeve is inserted. The

sleeve is inserted with the two small tong holes positioned upward.

Turn on the power to the calibrator by toggling the switch on the power entry

module. The fan should begin quietly blowing air through the instrument and

the controller display should illuminate after 3 seconds. After a brief self-test

the controller should begin normal operation. If the unit fails to operate please

check the power connection.

The display will begin to show the well temperature and the well heater will

start operating to bring the temperature of the well to the set-point temperature.

5.3 Power

Plug the dry-well power cord into a mains outlet of the proper voltage, fre

-

quency, and current capability. Typically this will be 115 VAC (±10%), 50/60

Hz (230 VAC ±10%, 50/60 Hz). Turn the dry-well on using the rear panel

9105/9107 13

5 Quick Start

“POWER” switch. The dry-well will turn on and begin to heat to the previously

programmed temperature set-point. The front panel LED display will indicate

the actual dry-well temperature.

The 9107 is field switchable between 115 V and 230 V. Refer to Section 7.2,

Switching to 230 V Operation, for information on switching the voltage.

5.4 Setting the Temperature

Section 8.3 explains in detail how to set the temperature set-point on the cali

-

brator using the front panel keys. The procedure is summarized here.

1. Press “SET” twice to access the set-point value.

2. Press “UP” or “DOWN” to change the set-point value.

3. Press “SET” to program in the new set-point.

4. Press “EXIT” to return to the temperature display.

When the set-point temperature is changed the controller will switch the well

heater on or off to raise or lower the temperature. The displayed well tempera-

ture will gradually change until it reaches the set-point temperature. The well

may require 5 to 10 minutes to reach the set-point depending on the span. An-

other 5 to 10 minutes is required to stabilize with ±0.1°C of the set-point. Ulti-

mate stability may take 15 to 20 minutes more of stabilization time.
